ANNAPOLIS, Md. (AP) — Tyler Allgeier ran for 132 yards and two touchdowns, and BYU put the clamps on Navy’s usually potent triple option in a season-opening 55-3 rout Monday night inside an eerily empty stadium at the Naval Academy.

The Cougars scored touchdowns on each of their first two possessions, led 31-0 at halftime and coasted to their most lopsided victory since a 70-6 blowout of Wagner in October 2015.

Allgeier averaged 9.4 yards per carry, Katoa ran for 80 yards and scored twice, and Wilson went 13 for 18 for 232 yards with two touchdowns before leaving in the third quarter.
